Definitions

  • the invention relates to a metallic or non-metallic wall, in particular for aeronautical structures such as tight tanks and a tank produced by such a wall.
  • US-A-2144945 shows a wall and a tank with the characteristics of the preamble of the claim 1, resp. of claim 12.
  • the present invention aims to provide a wall which overcomes the disadvantages of known walls.
  • the wall according to the invention includes the features of claim 1.
  • the connecting zones are produced by spot welding, ultrasonic welding, bonding, soldering, riveting and the like.
  • the edges of the plates are connected to forming areas for fixing the wall to a support structure.
  • the rigidity of the wall is variable by the choice of the number and the deviations of the connection zones and / or the choice of degree of bending of the plates.
  • the space between the walls is filled with a product of specific properties, such as a thermal product or acoustically insulating or non-flammable or mechanically favorable.
  • the process for producing such a wall is characterized in that the bending of the plates between the connection points is obtained by injection between the plates of a pressurized fluid.
  • connection of the plates is produced in particular by spot welding, ultrasound, bonding, soldering, riveting.
  • FIG 1 shows, by way of example, a parallelepiped tank made by assembling walls 1 according to the invention.
  • a wall according to the invention is carried out by superposition of two plates, for example of sheet metal made of aluminum alloy 2 and 3 connected to each other in connection zones 5, represented in the figures in the form of points for example of welding and the edges of which are tightly welded so as to obtain edges 6 which allow the mounting of the walls on a support structure.
  • we deforms the plates advantageously by injecting a fluid, advantageously of a liquid, under pressure in the space delimited between the plates so that the parts between the connecting zones 5 are bulged.
  • the bending rate i.e. the maximum deviation of the two plates 2 and 3 between the connection points is variable by varying the pressure of the injected fluid and of the forming tool used.
  • the distribution and arrangement of bonding areas on the wall surface composite are also variable.
  • the composite walls according to the invention can be produced in the form of flat or warped plates. It is enough for this purpose to place the plates superimposed preformed, during the "inflation" in a form whose space internal is correspondingly curved and delimited by faces spaced from each other by a distance equal to the desired thickness of the wall.
  • FIG. 4 illustrates, for comparison, the mechanical properties of a honeycomb composite wall according to the invention as shown schematically in FIGS. 5A and 58 with those of a conventional wall of the type shown in Figures 6A and 6B, i.e. consisting of a plate metal on which are profiled in the form of an ⁇ designated by reference 8.
  • Figure 4 shows the deformations of the plates as a function of constraints mechanical exerted on them. Measuring devices used for this purpose are shown in Figures 5C and 6C. These devices are of course identical.
  • the plate according to the invention bears the reference 1 (FIG. 5C) and the classic plate reference 1 '( Figure 6C).
  • the walls are embedded along their four sides and pressure is exerted on the surface of each wall test tube 1, 1 '.
  • the space in below the wall is produced in the form of a pressure chamber 10 and the pressurized fluid is introduced into this chamber through an opening 11.
  • the displacement of the walls at their center indicated in 12 is then measured. using a measuring device schematically shown in 13.
  • a measuring device schematically shown in 13.
  • Curve I represents the displacement of the wall 1 according to the invention and curve II those of the conventional wall 1 '.
  • the wall 1 according to the invention has a thickness e (FIG. 5B) equal to 80% of the thickness e ' of the classic wall.
  • the dimensions of test pieces 1 and 1 ' are 300 mm x 300 mm.
  • Figure 4 shows that despite this significant difference in terms of thicknesses, the honeycomb wall according to the invention has a marked rigidity greater (by about 50%) than that of the conventional wall.
  • the wall according to the invention still withstands values of 2 bars, the curve always keeping a linear look.
  • the mechanical characteristics of a wall composite according to the invention are clearly superior to those of walls classics. Since, to have similar rigidities, the wall dimpled according to the invention may have a much smaller thickness than that of a conventional wall, the use of the walls according to the invention, by example for the realization of tanks, is very advantageous. Indeed, for identical external dimensions, the tank made from walls according to the invention will have a useful volume substantially greater than that of a tank formed by conventional walls.
  • the advantage of the walls according to the invention is not limited to waterproof structural tanks but is valid in all areas involving the use of watertight walls, mechanically resistant under the effect high mechanical stresses, while ensuring space minimum.
  • the possibility of filling the internal space of the wall according to the invention of an appropriate product makes it possible to produce walls for example thermally or acoustically insulating, non-flammable or mechanically reinforced.
  • the filling product could for example be an incompressible elastic material.
  • the possibility of modify the arrangement of the welding points and the degree of bending of the plates, the walls according to the invention are adaptable to conditions specific applications.
  • the plates could be made of all materials suitable, metallic or non-metallic, and the bonding areas could be obtained by any suitable process, for example, by welding by points, ultrasound, bonding, soldering, riveting and the like.
  • each plate remains independent and a formation of cracks in the wall internal remains limited to this and leaks arrive in the space between the two plates from which they could be evacuated to the outside.
  • Another advantage of bonding is that the glue is placed in the median plane of the wall where the stresses are minimal or even almost zero.
  • connection zones are clamped between two pressure pads 15 as this is shown schematically in Figure 3A.
  • This maintenance of the bond when forming the quilted structure is preferably used also in the case of assembly of the plates by welding.
  • the plates can be made of materials homogeneous or heterogeneous and that the mean distribution lines of connecting points can be of any suitable geometric shape and desired such as circular or linear.
  • inflation it can be performed at room temperature or after heating the plates.
